The obvious endgame for Disney is to move all decent benefits of direct
DVC to a paid tier. My theory is that all discounted tickets, including Sorcerers Pass, will eventually become part of a paid program available to DVC direct purchasers.
Resale is still a superior option for most people. To sell more DVC, Disney needs to make DVC direct member benefits more worthwhile. However, straight up improving direct benefits doesn't allow Disney to extract additional money from existing direct contract holders.
My DW and I are new to DVC (but not Disney Parks), and in our purchasing direct/resale spreadsheets it simply didn't make financial sense for us to buy direct. We were looking at 150 points at Riviera direct, but that doesn't even get you enough days per year to make use of the Sorcerers pass at anytime of the year we can travel. If we had the option of buying discounted weekday discounted tickets, we
may have opted to still go direct.
